Hello Disha

As you had mentioned you got 84 percentile in JEE Mains , this year general cutoff in 89 percentile so if we compare that from previous years like

If one got 81 in Mains he had qualify for advance cutoff but he didn't get seat in nit or iiit in JoSSA if brlong to general category or even OBC category.

So i don't think you can get good  older NIT or IIIT or if you get one then branch may be not that good.

But still you can try for newer IIIT and NIT  ,you may got admissions into them in 3rd or 4th round of JOSSA counselling.

And, if you are from Home State quota then also you stand a chance to get seat in CLC Round in many NIT and IIIT.

Keep Trying

And if you qualify Advance then it would be great.

Thankyou
